nPr Calculates the number of possible permutations of n items taken r at a time. The order of objects is important, as in a race.
nCr Calculates the number of possible combinations of n items taken r at a time. The order of objects is not important, as in a hand of cards.
!The factorial of n is the product of the positive integers from 1 to n. n must be a positive whole number 69.
RAND Generates a random real number between 0 and 1. To control a sequence of random numbers, store an integer (seed value) ‚ 0 to
SE. The seed value changes randomly every time a random number is generated.
RANDI Generates a random integer between two integers, A and B, where A RANDI B. Separate the two integers with a comma.
For nPr and nCr, enter the first argument, press %6, select nPr or nCr, press V, and enter the second argument.
